App to display an included list of .pdf documents

I work for a regulatory agency that performs field inspections of water treatment facilities. It would be useful to have an app that would have:
1) a list of relevant document (I do not want the entire regulatory library of the State, just a small sub-set)
2) select an entry from the list and have it open on my device
3) have the documents be searchable (the documents are PDF)

Is there an app that I can modify to perform this?

I know there are document readers available, but I do not know how to create a document package for access.

Also, a icon on the screen to open the app with the documents would be beneficial (there are others in my department that would use this app).
